The Marantz KI Signature MkII although old, about 15 years, is still a classy cd player.

With the Burson upgrades, Jitter Clock and twin Op Amps, it becomes a truly refined instrument of joy. The Marantz is partnered with a Quad 44 pre (upgraded) and 606 Power amp with a good pair of ESL 63’s.

Before the upgrade the music was already fantastic – now it’s even more so. There is more than a subtle step up in performance.

I know the difference and the difference is palpable. The upgrade is worth every cent.
